-Lua is a powerful, light-weight programming language designed for
-extending applications. Lua is also frequently used as a
-general-purpose, stand-alone language.
+Lua is a powerful, fast, lightweight, embeddable scripting language.
 
-Lua combines simple procedural syntax (similar to Pascal) with
-powerful data description constructs based on associative arrays and
-extensible semantics. Lua is dynamically typed, interpreted from
-bytecodes, and has automatic memory management, making it ideal for
-configuration, scripting, and rapid prototyping.

-Lua is a language engine that you can embed into your application.
-This means that, besides syntax and semantics, Lua has an API that
-allows the application to exchange data with Lua programs and also to
-extend Lua with C functions. In this sense, Lua can be regarded as a
-language framework for building domain-specific languages.
-
-Lua is implemented as a small library of C functions, written in ANSI
-C, and compiles unmodified in all known platforms. The implementation
-goals are simplicity, efficiency, portability, and low embedding cost.
-The result is a fast language engine with small footprint, making it
-ideal in embedded systems too.
+This version is a preferred choice for new Lua modules.
